Image recording apparatus having device for adjusting position of mask members

摘要

An image recording apparatus using a set of mask members and having mask position adjusting device. A transparent mask member supporting plate is provided at the exposure position. Each of the mask member is delivered upon the mask member supporting plate by two pairs of rollers. In this mask delivery, a mask image surface faces upwardly. An elongated photosensitive recording medium is positioned immediately above the mask member supporting plate so as to guide the medium at the exposure position. Further, an exposure device including a light source and color filters is positioned below the mask member supporting plate. The mask member undergoes positional adjustment at the exposure position. For this, the mask member supporting plate is supported on a positioning frame which is movable in a direction perpendicular to the mask member moving direction. The position of the mask member with respect to the running direction thereof is controllable by controlling rotations of two pairs of rollers, and the mask position with respect to its tranverse direction is controllable by controlling the movement of the positioning frame.
